GEORGE S. EDWARDS, OF ENID, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO JAMES M. EDWARDS, OF OSGEOLA, PENNSYLVANIA.

AUTOMATIC PRINTING-FRAME.

To all whom it may concern:

Be it known that I, GEORGE S. EDWARDS, a citizen of the United States, residing at Enid, in the county of Fulton and State of Pennsylvania, have invented new and useful Improvements in Automatic Printing- Frames, of which the following is a specification.

My invention relates to improvements in photographic printing frames, and broadly and generally speaking it comprises a body, a back hingedly secured to the body, and a front hingedly secured to the body.

One object of the invent on is the provision of a photographic printing frame where in the back, upon being released, is automatically thrown into and held in opened position, whereby to permit the printing paper to be readily and quickly applied and re moved from the frame.

A further object of the invention is the provision of a photographic printing frame which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.

lVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawing, wherein: Figure 1 is a longitudinal sectional view of a photographic printing frame constructed in accordance with my invention. Fig. 2 is a sectional view taken on a vertical plane extending transversely of the frame, the back being shown in opened position. Fig. 3 is a detail view in side elevation of the latch and latch operating means. Fig. 4 is a sectional View taken on a plane extending vertically and transversely through one end of the body, illustrating the manner in which the dog and the plunger of the latch operating means are mounted. Fig. 5 is a top plan view of a fragmentary portion of one corner of the body of the printing frame.

Referring to the drawing by reference numorals, 1 designates the body, 2 the front, and 3 the back of my improved photographic printing frame.

The body 1 consists of a rectangular frame and therefore comprises ends 4 and 5 and sides 6. As shown to the left of Fig. 1 of the drawing, the end 4 is greater in horizontal Specification of Letters Patent.

transverse extent than the end 5, and is provided with a recess 7 which opens out through the under side thereof, (see Fig. 4 of the drawing). The end 5 is provided in its inner side with a notch 5*, which permits the operator to engage the paper with his finger when it is found necessary to loosen the paper before it can be removed from the frame. An opening 8 extends from the recess 7 to and through the inner side of the end 4, and an opening 9 extends from the recess to and through the upper side of the end.

The front is secured at one end to the end 4 of the body by means of hinges 10, and, like the body, consists of a rectangular frame. The inner and outer surfaces of the sides and ends of the front 2 are coincident with the inner and outer surfaces of the sides and ends of the body 1. The sides and ends of the front 2 are rabbeted as at 11 to permit the application of a glass panel 12, which is se cured in applied position by means of putty or other suitable material 13. In view of the manner in which the front 2 is connected to the body 1, said front may be swung toward and away from the body, that is it may be opened and closed. The front 2 is adapted to be secured in closed position by means of a hook 14 which is pivotally secured to the front by means of a pin 15 for engagement with a pin 16 secured to the body 1.

The back 3 is solid and rectangular and is secured at one end to the end 4 of the body 1 by means of hinges 17, whereby it may be swung into closed or opened position. W' hen the back 8 is in closed position it lies within the body 1, and it is adapted to be secured in such position by means of a spring latch 18. The spring latch 18 is secured at one end to the end 5 of the body 1, and the free end thereof is disposed for engagement with a keeper 19 secured to the free end of the back 3. A rod 20 is slidably mounted in a bore 21 which extends diagonally and opens out through the ends of the back 3. The keeper 19 is provided with an opening 22 which registers with one end of the bore 21, the opposite end of the bore registering with the opening 8 in the end 4 of the body 1. The rod 20 is greater in length than the longitudinal extent of the back 3 and one end thereof passes through the opening 8 into the recess 7 when the back is in closed position, (see Figs. 1. and

4 of the drawing). An angular dog 23 is pivotally mounted in the recess 7 on a pin 24, the vertical member of said dog being in position for engagement with that end of the rod disposed in the recess. The dog 23 supports a plunger 25 which passes through the opening 9 in the end 4 of the body.

The connection between the spring latch 18 and the plunger 25 is such that when the plunger is depressed the latch is thrown out of engagement with the keeper 19. When the spring latch 18 is thrown out of engagement with the keeper 19, that is to say, when the latch is in back releasing position, the back may be swung open. The back 3 when released is automatically opened by means of a spring pressed bolt 26 which is mounted in a socket 27 located in the back and opening out through the attached end thereof. The bolt 26 is provided with a stem upon which a coiled expansion spring 28 is mounted said spring being located between the bottom wall of the socket 27 and the inner end of the bolt 26. The movement of the bolt in both directions is limited by means of a pin 29 which is carried by the back 3 and which passes through an opening 30 formed in the bolt.

The manner in which my improved photographic printing frame may be used may be stated to be as follows. After the hook 14 has been thrown out of engagement with the pin 16 the front 2 is opened and the film is placed upon the glass panel 12. After the film has been placed on the glass panel 12 the front 2 is closed and the hook 14 swung into engagement with the pin 16. The operator then moves the plunger 25 downwardly whereupon the back 3 is automatically opened. After the back has been opened the printing paper is placed upon the frame after which the back is swung into closed position. The back 3 is preferably provided with a pad 31 of any suitable material. The end 4 and the contiguous end of the front 2 provides a base by which the frame may be handled. After the picture has been printed the operator grasps the base with his left hand and forces the plunger 25 downwardly, whereupon the back is again automatically opened, permitting him to remove the printed paper.

It should be apparent from the above description, taken in connection with the accompanying drawing, that I provide a photographic printing frame which is so constructed as to permit the film and printing paper to be readily and quickly applied and removed, and which may be manufactured and sold at a comparatively low cost.

Changes in the form, proportions and minor details of construction may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.
